Why use bleach to clean a dishwasher?

Bleach is a powerful cleaning solution that can be great for getting rid of tough stains, killing bacteria, and making unpleasant odors disappear.

It’s especially good at removing stubborn mold and mildew stains that other cleaning solutions might not be able to tackle.

When used properly and in the right amount, bleach can be a safe and effective cleaning solution for plastic dishwashers. But, it’s important to remember that it’s not safe for use on dishwashers with a stainless-steel interior, as it can damage the finish and internal parts.

Can you clean a stainless-steel dishwasher with bleach?

While bleach is a powerful cleaning solution that can kill bacteria and remove tough stains, it is not a good choice for cleaning a stainless-steel dishwasher.

Stainless steel is more delicate than plastic, and bleach can damage the finish, leaving behind unsightly marks and even rust.

Additionally, bleach can corrode the rubber seals around the dishwasher door, causing leaks and other damage.

There are other effective and safe cleaning solutions that can be used instead, such as vinegar, baking soda, and citric acid.
